Abstract
An electronic timepiece includes two oscillator circuits (a,b) each of which has a piezoelectric oscillator (1, 2), the piezoelectric oscillators having materially different oscillation frequencies. Each oscillator circuit is connected to a respective frequency divider circuit (18, 19). The frequency divider circuits have different division ratios so that the output signals thereof have substantially the same frequency. <IMAGE>
